Description
CHIPLESS KEY HEAD AND ADAPTER FOR AN ELECTRONIC KEY
CROSS-REFERENCE TO PRIORITY APPLICATIONS
[0001] This international application claims the benefit of and priority to U.S. Provisional Patent Application Serial No. 61/640,710, filed April 30, 2012, in the U.S. Patent and Trademark Office, and U.S. Non-provisional Patent
Application Serial No. 13/873,469, filed April 30, 2013, in the U.S. Patent and Trademark Office, both of which are hereby incorporated by reference in their entirety.
BACKGROUND OF THE INVENTION
[0002] The invention relates to keys and particularly to modular keys and key assemblies that incorporate electronic components such as transponders for remote signaling to a lock .
[0003] Key and lock systems have progressed over the years such that traditional keys with blades that fit into a cylinder or other lock mechanism are being improved with electronic systems. Many keys, particularly in the
automobile industry, have the standard key blade with milling and bitting cuts required to allow the key to engage a standard lock. In addition, modern keys, or "smart keys," also include electronics such as a transponder that must be present and transmit an appropriate code for a driver to start the ignition on a vehicle.
[0004] U.S. Patent No. 7,380,428 (Morehart et al. 2008) illustrates one kind of transponder key assembly with a key blade and head assembly. The key blade has appropriate milling and bitting cuts to engage the ignition lock. As noted in the Morehart 28 patent, most transponders utilize the RFID technology in which an electromagnetic pulse from lock circuitry energizes the transponder in the key head. The transponder sends an electronic code to circuitry in the automobile allowing the ignition to start the car. The 28 patent is characterized in its disclosure of a key blank with a distinctive opening in the key head that receives a transponder holder shaped to fit within the distinctive opening. A removable transponder fits within the holder. Numerous kinds of keys are disclosed, each with a different shape for the opening in the key head and a corresponding transponder holder. In other words, each kind of key that is used for a special purpose (i.e., a particular vehicle), has a distinctively shaped opening that matches a respective transponder holder. The key head maintains the transponder holder in a secure position, but the transponder holder is removable from the key head by a specialized tool. This way, the transponder can be removed if necessary to fit into a replacement key with a matching key blade. This technique saves money if the key blade needs to be replaced by not requiring complete replacement of the key transponder and the transponder holder.
[0005] European Patent Application Publication No.
EP0955430 (Davis et al. 1999) discloses another combination
of a key and transponder in which the key head defines a slot into which a transponder holder fits snugly. A molded sheath fits around the key head, so the transponder of this early device was not removable.
[0006] Even with keys that have fittings suitable for holding a transponder, there exists a need in the art of smart keys for a key and transponder assembly that promotes efficient use of materials and allows for suitable
transponder replacement without reproducing the entire key structure .
SUMMARY OF THE INVENTION
[0007] The invention is directed to an adapter (or
transponder adapter) that fits within a key assembly and is capable of holding more than one kind of transponder within the adapter (i.e., the adapter accommodates transponders that have respectively unique shapes, sizes, and
dimensions) . In this way, the adapter allows for a single piece, the adapter, to hold transponders that are designed for a respective purpose and therefore have a particular profile. For purposes of this invention, the term
"transponder" includes any assembly (30, 32, 34, 36) that incorporates a transponder therein. As such, the term
"transponder" includes the electronic device known as a transponder along with any housing or holder encapsulating the transponder.
[0008] The transponder adapter shown herein allows for multiple kinds of transponders to be placed in a single kind
of key. Similarly, the transponder can be removed from that key and recycled for use in a different key.
